WINDOW-SASH CONSTRUCTION.

Specification of Letters Ifatent.

Patented Sept. 1, 1914.

Application filed March 6, 1913. Serial No. 752,447.

To all 'w/wqnit may POW/(6TH Be it known that I, HENRY W LANDOL'l,residing at Brooklyn, in the county of Kings and State of New hork, haveinvented certain new and useful Improvements in lViiidow-SashConstruction, of which thefollowing is a specification.

This invention relates to window sash coir struction, and theparticularobject thereof is. to provide a simple design therefor,whereby a sash of eXceptional strength may be manufactured atcomparatively small cost. i

A further objectis to provide a structure formed of parts so shaped andarranged as to be capable of easy asse i'iblage, and to adapt said partsso that, when assembled, they will interlock with each other in sulstantially immo able relation, whereby each will lend its strength tothe other in with standing strains to which the sashmay be subjected. v

A. further, and somewhat more detailed object, is to provideintersecting base or body members forming a lattice, and to provideseparately formed molding pieces for positively locking the base memberstogether. I H

Other objects and ainis'of the invention, more or less specific thanthose referred to above, will. bein part obvious and in part pointed outin the course of the following description of the elements,combinations, arrangements of parts and applications of principlesconstituting the invention; and the scope of protection contemplatedwill be indicated in the appended claims.

In the accompanying drawings which are to be taken as a part of thisspecification, and in which I have shown a merely pre ferred form ofembodiment of the invention: Figure 1 is a detail perspective view of aportion of a window sash constructed in accordance with the provisionsof this invention, the marginal frame of said sash heing illustrated indotted lines, and parts ofthe lattice work of said sash beingillustrated in fully assembled relation, and other parts beingillustrated in process of assembling; and Fig. 2 is an enlarged detailsectional section being taken on the plane of line 2-2 1, looking in thedirection of the Referring to the drawings for. a detailed descriptionof the parts and their method of assembling, the reference nun'ieral 1ndil l l 4 I catcs a plurality of vertically disposed lattice pieces,which will be hereinafter referred to as the vertical base members.

They extend from top to bottom the -martice pieces extendingtransversely 'of the base members 1 preferably from side to side of thesash frame, and being capable 'of'attachment to said side pieces in anysuitable manner. These will be hereinafter referred to as the horizontalbase member s, andmay also be in any number according the height of thesash and according to the height of the glass section to be disposedbetween them. The base members '1 and 8 therefore are adapted to definea plurality of rectangular areas within the marginal frame 2 of thesash, each of said areas he closed or filled with rectangular pieces ofglass l, as will be understood. i

The base members 1 and 3 are preferably of substantially identical crosssection, each comprisinga web portion 5 and a head portion 6 extendinglongitudinally at one edge of the web and forming therewith a T-bar.

T 1e opposite longitudinal edges 7 of the head portion 6 of each of thepieces 1 and 3 are inclined relatively to each other, as best seen inFig. 2, from the'outer surface of the head inwardly toward the web 5 fora purpose presently to be described. These base members intersecteacliother, and at the sevi v e i i p eral points of intersection theyare provided with cut out portions or slots 8 and 9 respectively, sothat the pieces may be nested together in a Well-knownmannerl It ismaterial which of the sets of base members are provided with the slotsextending through the head portion thereof, biitfdr the purpose ofillustration the'inembers 3, extending from side to side of the sash areprovided with such slots. With thisunderstanding several of the members3 may have their slots 9 engagedwith one only of the members 1, thesingle member 1 serving to hold the several members 3 in spacedrelation, this being done before anyof the n em bers are inserted withinthe frame 2.

jlrinolding piece 1,0, having dove-tailed slot 11 extendinglongitudinally in its under surface, is attached to the base member 1 bytelescoping the head portion 6 of the member 1 within the dove-tailedgroove 11 of the molding, the opposite inclined edges 7 of the headserving to positively retain the molding against detachment laterallyfrom the head. This molding piece 10 is of continuous cross sectionbeing preferably entirely devoid of any notches or cut-away partswhatever so as to attain maximum strength. 1

In the case of the first base member 1 to be assembled, the molding 10may be attachedto the base before the said base is assembled with thehorizontal base members, but it may be here noted that in assemblingsubsequent base members 1, this is not the case, as Will. be presentlyapparent.

Molding pieces 1.2, slmilar to the piece 10, except-as to length, areapplied to the head portions 6 of base members 3, the dovetailed groovesof said. molding pieces 12 engaging with the inclined sides of the headportions 6 of base members in the same manner as does the molding 10with the head portion of the base member 1, above referred to. V

The molding pieces 12 are cut to a length commensurate with the spacedesired between the vertical members of the lattice, that is, with theslots 9 formed in the base members 3, and the opposite ends of themolding pieces 12 are coped away so as to form relatively overhangingparts 18 shaped to fit closely about shoulder portions 1 1 formed on therelatively outer surface of the molding piece 10 as best seen in Fig. 2.The molding pieces 12 are telescoped longi tudinally over the headportion 6 of the base members 3 from opposite directions until the ends13 thereof engage closely over the shoulder portions 1 1 of the molding10.

lVith the structure thus far assembled, a.

second vertical base member 1 may be inserted, or nested, Within thenext row of slots 9 of the base members 3. Such a base member 1 isillustrated at the right of Fig. 1 in position to be engaged in theslots 9 of the base pieces 3 after the lower molding piece 12 has beenmoved to the left to uncover the slot 9 in the lower base member 3.

tively and rigidly lock the base member 1- to each of the base members 8of the structure. The lock is further strengthened by 1 be assembled.

the placing of other molding pieces 12 at the opposite, or right hand,side of the'molding 10 just placed.

Each subsequent vertical base member 1 must be attached in the samemanner as that just described, and molding sections 12 applied to thebase members 3 before the next succeeding vertlcal base member 1 may Themoldings 10 and 12 are easilv applied by telescoping over the heads ofthe base members, and are as easily detached there from in the samemanner, no tools being required for either operation. I When the fulllattice portion of the sash is thus assembled, it is inserted within themarginal frame 2 which may have been already constructed, or which maybe built about the lattice and attached thereto in any desiredmanner,the details of which attachment are not important to the features ofthis invention, the only essential of the frame being to lend addedstrengthto the lattice and provide shoulder portions as at 15 forpreventing longitudinal detachment of the outer molding pieces 12 andalso of the molding pieces 10.

It may be here noted that, in the completed lattice, each'of the moldingpieces 12 is positively held against longitudinal movement bytheengagement of its opposite ends with thesides of the moldings 10 sothat both the moldings 10, and their base members 1, are held by eachmolding piece 12, and it is practically impossible to disassemble thelattice exceptby telescoping the moldings 10 longitudinally off of thebase members 1. This may however be done whenever desired since themoldings are all readily detachable.

The head porti is cut out for a short distance at opposite sides of theslots 9 as at 18 for accommodating the over-hanging portions of themoldings 10, forming a sort of groove through Which the moldings 10 mayslide. The overhanging portions 13 of the moldings 12 also provide asort of groove through Which the molding 10 may slide. I

The web portions 5 of the base members 1 and 3 define the rectangularareas within which the glass sections 41 are confined, and. the undersurface portions 16 of the moldings 10 and 12 provide a shoulderextending around. said areas against which the inner surface of theglass sections rest. Retaining members 17 for the glass sections are.at-{ tached to the web portions 5 and engage the outer surface of theglass to hold it against detachment. These retaining pieces may beformed of any material, but preferably comprise angle sections arrangedwith one leg resting against the Web 4: and with the other leg restingagainst the surface of the glass, the first mentioned leg beingconnected to on 6 of the cross pieces 3 the web by a screw or otherdevice 19 which may obviously extend throughthe web and serve as theretaining means for a similar glass holding element at the opposite sideof theweb, or not, as desired.

The continuous uninterrupted formation of the molding pieces 10, it willbe noted, add very materially to the strength of the vertical basemembers 1. These base members being formed with notches Sin their webportions spaced from. theheadthereoit' are considerably weakened, andthe continuous integral formation of the molding attachedfto theheadwill in a great measure compensate for the loss occasioned by thepresence'oii the slots 8. The moldingsl0,by their intimate engagementwith the molding pieces 1.2, will transmit their strength through saidmolding pieces 12 to the base members 3. The notches in the base members3, being formed through the head portion thereof, leaves a portion ofthe web only to resist lateral strains, but the interlocking relation ofthe ends of the molding f-lll pieces 12 with the moldings 10 will fullycompensate for the loss sustained in the cutting away of the headportion.

Forces tending to bow out the window from the .inside, that is, from theside to which the moldings are attached, will be resisted by thevertical pieces 1, which, with the continuous molding pieces 10 fixedthereto, will effectually resist such strains, the molding beingrelatively under compression longitudinally, and the outer longitudinaledge of the web portion 4t being relatively under tension. The strengthof the struc ture in resisting forces from within is materiallyincreased by the base members 3 where the moldings 12 will also berelatively under compression, and the outer longitudinal edges of theweb portions of the base member being relatively under tension. Thesides of the apertures 9 will grip against the opposite side surfaces ofthe web 5 of the base members 1, and this in effect, will complete theweb of the members 3 to their full cross section. The ends of themolding pieces-12 will wedge against the opposite sides of the moldingsl and this also will, in effect, completethe moldings 12.

Forces tending to bow the structure in aardly will be opposedprincipally by the vertical base members 1, which, it will be noted, arefully capable of withstanding a very considerable pressure fromWithoutfor the reason that they will. present to such forcessubstantially their full cross section unimpaired continuously of theirlength, the sides of the notches 8 gripping against the oppositesurfaces of the webs of the base members 3. The connecting portions atthe notches 9 of the base members 3 will also serve to resist forcesfrom without.

The interlockingengagement of all of the parts will, of: course, serveto resist forces both from within and from without.

It is thus seen that I have provided a structure of simple parts, easilyand cheaply manufactured, and capable of being assembled into anexceptionally rigid lattice by 'matter contained in the abovedescription or shown in the accompanying drawing v intersecting basemembers, and molding pieces detachably carried by said base members andserving to lock said base members together.
